Abstract

The present invention provides an unsealed envelope that prevents the contents from being accidentally broken when unsealed. An opening-type envelope is formed by continuously forming an opening perforation 6 (an opening separating portion) on a paper envelope body so as to be endless. Reference numeral 5 denotes a breakage prevention sheet made of a cellophane sheet or the like, and is attached by an adhesive material 9 so as to be positioned at the perforation 6 on the inner front surface of the envelope body. The order of preparation of the unsealed envelope is that the lower part 11 of the base sheet 10 is folded on the central part 12 to which the sheet 5 for damage prevention is stuck, and the upper part 14 is folded on the upper part 14 to bond the edges together. The bottom part 15 is folded and pasted on the upper part 14 and the lower part 11. [Selection] Figure 3

Description

  The present invention relates to an improvement of an open envelope.

  As an envelope, there is an unsealed envelope in which a separation portion by a perforation is formed and can be easily opened by the separation.

  However, in the case of this unsealed envelope, the contents may be accidentally broken together when the envelope is separated at the time of unsealing.

  This invention has been made in view of the above circumstances, and provides an unsealed envelope in which contents are prevented from being accidentally broken when unsealed.

  In the present invention, in the opening-type envelope provided with an opening separating part on the envelope body, a damage preventing sheet is disposed along the inner surface side of the separating part to prevent the contents from being damaged due to the opening operation by the separating. It becomes the composition which becomes.

  According to the above configuration, even if the contents may be held together when the separation part is separated at the time of opening, the separation prevention is prevented by the presence of the damage prevention sheet, and the contents are prevented from being broken. The

  The envelope body is equipped with a window, and the damage prevention sheet is transparent and pasted on the inner surface side of the window, so that the damage prevention sheet is arranged as a configuration for extending the window sheet used conventionally. The envelope can be easily manufactured. Further, the attachment of the breakage prevention sheet can be easily performed by using the adhesive material, and the envelope can be recycled by removing the breakage prevention sheet made of a plastic sheet. In addition, it is formed continuously so that the unsealing part for opening is endless, and the entire side to be separated by separating and unsealing is removed, so that the other side remains in a clean shape and the contents of the envelope are removed. Can be used to store.

  According to this device, it is possible to obtain an unsealed envelope in which contents are prevented from being accidentally broken at the time of unsealing.

  FIG. 1 is a front view of an embodiment of an envelope of the present invention, FIG. 2 is a rear view thereof, and FIG. The unsealed envelope 1 has an opening perforation (opening separating portion) 6 formed on a paper envelope body 2. As can be seen from FIG. 3, the perforation 6 is continuously formed so as to be endless. Reference numeral 5 denotes a damage prevention sheet made of a cellophane sheet or the like, which is attached and attached by an adhesive material 9 so as to be positioned on the inner surface side of the perforation 6 at the upper front surface of the envelope body 2.

  The unsealed envelope 1 is manufactured by folding the lower side portion 11 of the base sheet 10 on the central portion 12 to which the damage preventing sheet 5 is attached, and the upper portion 14 being folded on the upper portion 14. And the upper portion 14 are bonded to each other, and the bottom portion 15 is further folded and pasted on the upper portion 14 and the lower portion 11.

  As shown in FIG. 4, the opening-type envelope 1 is opened by first separating and starting up the finger-hook portion 20 on the back side formed by the perforation 6, pressing the X position with one hand, Holding the Y position in the vicinity with the other hand, the perforation 6 is separated, and further, the perforation 6 is separated by pulling to the left side. As a result, the separation side A that integrates the finger rests 20 is separated from the other side B along the perforation 6 that is divided on both sides, as shown in FIG.

  While holding the Y position in the vicinity of the finger hook 20 with the other hand and cutting the perforation 6, the contents Z may be held together. Since the breakage preventing sheet 5 is provided, the separation is prevented. In that case, only the envelope main body 2 is held again at the Y position for separation, so that the damage to the contents Z that has conventionally occurred can be reliably prevented. The finger hooking part 20 by the perforation 6 is provided, and the perforation 6 is provided with the curved part 6a, so that the separation work can be performed easily and smoothly.

  Further, when the above-described separation is performed, the X position of the breakage prevention sheet 5 is pressed with the right hand, so that the breakage prevention sheet 5 remains in that position and is stuck with the adhesive 9 as shown in FIG. As a result, the side A is peeled off from the damage preventing sheet 5. Further, the side A is completely removed from the side B because the perforation 6 is also provided at the edge 21 of the envelope body 2 and is endless. Finally, release the hand from position X and pull out the exposed part of the damage prevention sheet 5 with a little force, so that the attachment part by the adhesive material 9 is peeled off and the damage prevention sheet 5 is completely removed from the side B. To be removed. The damage prevention sheet 5 does not necessarily have to be attached with the adhesive material 9 on the side B. However, when the contents Z are attached and fixed, the end of the damage prevention sheet 5 becomes an obstacle. It can be done smoothly.

  With side A completely removed as described above, side B remains in a clean shape so that side B can be used to store contents Z as shown in FIG. Moreover, the opening type | mold envelope 1 becomes a thing suitable for recycle use because the sheet | seat 5 for damage prevention which consists of a cellophane sheet can be easily removed from the side A and the side B with opening.

  FIG. 7 is a front view of another embodiment of the unsealed envelope according to the present invention, and FIG. 8 is a developed view of the embodiment of the base sheet used for manufacturing the envelope, showing the inner surface side thereof. The unsealed envelope 1 is provided with a window 3 for displaying a destination address at one upper portion on the front side of the envelope body 2. In this embodiment, the transparent sheet that covers the window 3 from the inside is also used as the damage prevention sheet 5, and the other configuration is the same as that of the above embodiment, and the function and effect thereof are also achieved. .
